Scottish vowel length rule

The Scottish vowel length rule (also known as Aitken's law after A. J. Aitken, the Scottish linguist who formulated it) describes how vowel length in Scots, Scottish English, and, to some extent, Mid-Ulster English is conditioned by the phonetic environment of the target vowel. Certain vowels are long before /r/, voiced fricatives or a morpheme boundary. Also, vowels in word-final open syllables are long.
